TABLE 3
GUIDANCE AND MINDRAY DECLARATION—ELECTROMAGNETIC IMMUNITY
The system is intended for use in the electromagnetic environment specified below. The
customer or the user of system should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to
any part of system, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.

where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and d is the recommended
separation distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey, should be
less than the compliance level in each
frequency range.
Interference may occur in the vicinity of
equipment marked with the following
symbol:

to 2.5 GHz
3V/m
Note 1 At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
z Field strengths from fixed transmitters, such as base stations for radio (cellular /
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength
in the location in which system is used exceeds the applicable RF compliance
level above, system should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
reorienting or relocating system.
z Over the frequency ranges 150kHz to 80MHz, field strengths should be less than
1V/m.
